Multigigabit access for workstations and wireless backhaul
Plan link speed and endpoint power separately when upgrading campus access.
Deployment scope
Plan link speed and endpoint power separately when upgrading campus access. Survey NIC and AP uplink modes, installed copper cabling and peak traffic. Calculate aggregation load before selecting access speed. Keep PoE startup and loss-of-one-supply capacity in a separate power worksheet.
Component decisions
- C9300X-48TX-E is a data switch; do not infer PoE from its multigigabit ports.
- Check the PoE budget and power configuration for C9300X-24HX-E against the connected endpoints. C9300-24UX variants are a different platform.
- C9300X-NM-4C has host-specific support. Check the current host matrix rather than assuming every C9300X accepts the same uplink module.
Acceptance plan
- Verify negotiated speeds on the installed cable routes.
- Exercise busy-hour uplinks with realistic traffic and endpoint power demand.
- Record host, uplink module, software and power supply part numbers.
Configuration boundary
An endpoint may need a faster data link, more electrical power, or both. Those are separate specifications. Buying by the largest speed number can leave an AP without power or move the bottleneck to an undersized uplink.
